DURANGO, COLORADO—Rangers at Mesa Verde National Park are asking the public for ideas to relieve congestion and overcrowding at its most popular sights. “It is no secret Chapin Mesa gets overrun. The plan has always been to redirect visitors and traffic to Wetherill Mesa, but that has not worked out as well as we had hoped,” deputy superintendent Bill Nelligan told The Cortez Journal. For example, visitors may now prefer to walk, bicycle, or take a bus through the park, rather than drive pollution-producing private vehicles through its winding, narrow roadways. Heavy crowds also damage the kivas. “Improving opportunities like trails separate from the road, and more self-guided areas, so visitors have a sense of exploration and discovery is the goal of the plan,” he said.
